1.Antero-posterior
Position of the Patient and Cassette
• From the lateral position, the patient’s arm is externally rotated.
• The arm is then extended fully, such that the posterior aspect of the
entire limb is in contact with the tabletop and the palm of the hand
is facing upwards.
• The unexposed half of the cassette is positioned under the elbow
joint, with its short axis parallel to the forearm.
• The arm is adjusted such that the medial and lateral epi- condyles
are equidistant from the cassette.
• The limb is immobilized using sandbags.

Direction and centring of the X-ray beam
• The vertical central ray is centred through the joint space
2.5 cm distal to the point midway between the medial and
lateral epicondyles of the humerus.

2. Lateral
Position of patient and cassette
• The patient is seated alongside the table, with the affected
side nearest to the table.
• The elbow is flexed to 90 degrees and the palm of the hand
is rotated so that it is at 90 degrees to the tabletop.
• The shoulder is lowered so that it is at the same height as
the elbow and wrist, such that the medial aspect of the entire
arm is in contact with the tabletop.

• The half of the cassette being used is placed under the
patient’s elbow, with its centre to the elbow joint and its short
axis parallel to the forearm.
• The limb is immobilized using sandbags.

3.Ulnar groove - Axial
Position of patient and cassette
• The patient is seated alongside the X-ray table, with the
affected side nearest the table.
• The elbow is fully flexed, and the posterior aspect of the
upper arm is placed in contact with the tabletop.
• The cassette is positioned under the lower end of the
humerus,with its centre midway between the epicondyles of
the humerus.
• With the elbow still fully flexed, the arm is externally rotated
through 45 degrees and supported in this position.
